This study was carried out to evaluate the manufacturing characteristics of organic liquid fertilizer with poultry manure, soybean meal, and rice bran at plastic house in Chungbuk Agricultural Research and Extension Service. Treatment was given 3 treatments; poultry manure+soybean meal (PM+SM), poultry manure+rice bran (PM+RB), and soybean meal+rice bran (SM+RB). The obtained results from this study were summarized as follows; The pH in liquid fertilizer was consistently increased in PM+SM treatment, and was increased after decreased at early season in PM+RB and SM+RB treatments. The electriacl conductivity(EC) in liquid fertilizer was rapidly increased from $2^{nd}$ weeks to $4^{th}$ weeks after fermentation in PM+SM and PM+RB treatments, and was rapidly increased from $4^{th}$ weeks to 6th weeks after fermentation in SM+RB treatment. The amount of $H_2S$ gas occurrence was the highest as $1,200\;mg{\cdot}kg^{-1}$ in early season, and was the lowest as $50\;mg{\cdot}kg^{-1}$ at $12^{th}$ weeks after fermentation of organic liquid fertilizer. The temperature of organic liquid fertilizer was stabilizing in $4^{th}$ weeks after fermentation. The yield of well of nitrogen, phosphate, and potassium was increased with increasing fermentation periods. It was not change from $4^{th}$ weeks after fermentation in content of calcium, magnesium and sodium in organic liquid fertilizer.

본 연구는 고추 논 비가림재배 시 비가림형태가 생육 및 수량에 미치는 영향을 구명코자 수행하였다. 시험품종은 ‘금마루’이었다. 비가림형태는 노지(대조구), 간이비가림(2줄재배, 2R), 간이비가림(4줄재배, 4R), 하우스(House) 등 4처리를 하였다. 초장은 House 처리에서 가장 우수하였으며, 엽장과 엽폭은 비가림형태간에 차이가 없었다. 생과중과 건과중은 House > 4R > 2R > 대조구순으로 많았다. ASTA 값은 처리간에 일정한 경향을 나타내지 않았다. 역병, 흰가루병, 세균성점무늬병은 전혀 발생하지 않았고, 탄저병은 노지에서만 발생하였다. 응애, 총체벌레, 담배가루이는 모든 처리에서 발생하지 않았다. 진딧물, 담배나방, 바이러스는 모든 처리에서 동일한 수준으로 발생하였다. 본 연구에서 얻어진 결과는 고추 비가림재배는 건고추 수량 및 상품성 증대뿐만 아니라 병해충의 발생 감소시킬 것으로 기대된다. This study was carried out to investigate the effects of rain-shelter types on growth, and fruit quality of red pepper (Capsicum annuum, ‘Kemmaru’) cultured in paddy. Applied rainshelter types were outfield (control), simple rain-shelter plastic house with 2 rows (2R), simple rain-shelter plastic house with 4 rows (4R), and perfect plastic house (House). The plant height was the highest in Houses treatment. There was no difference in leaf length and width among the rain-shelter treatments. The fresh and dry weight of red pepper was high in order of House > 4R > 2R > Control. The ASTA value is irregular tendency among the treatments. Hunter’s color value ‘a’ and ‘b’ was not different from among the treatments. Phytophthora blight , powdery mildew, bacterial spot were not occurred in all of treatments, and Anthracnose was only occurred in control. Mite, Microcephalothrips abdominalis, and Bemisia tabaci were not occurred in all of treatments, and aphid, Helicoverpa assulta, and virus were occurred all of treatments as same degree. Our results will provide rainshelter cultivation of red pepper can be increase dry yield and decrease disease and insects.

본 연구는 식물공장 인공광원이 방풍나물의 생육 및 수량에 미치는 영향을 구명코자 수행하였다. 식물공장의 인공광원으로 형광등(FL), LED R:B(2:1, RB), R:B:W(2:1:3, RBW), R:B:G:W(2:1:0.5:3, RBGW) 등 4처리를 사용하였다. 엽중은 RBW와 RB가 FL과 RBGW 보다 우수하였다. 엽장과 엽후는 처리간에 유의성을 나타내지 않았다. 잎의 명도는 초장과 같은 경향을 나타냈다. 총 페놀함량은 RB가 105.77mg·100g<SUP>-1</SUP> GE로 가장 높았고, RBW 92.52mg·100g<SUP>-1</SUP> GE, FL 89.08mg·100g<SUP>-1</SUP> GE, RBGW 82.00mg·100g<SUP>-1</SUP> GE 순으로 높았다. 총 플라보노이드 함량은 모든 처리에서 검출되지 않았다. 비타민 C함량은 RB에서 가장 높았고, FL에서 가장 낮았다. 총 식이섬유소 함량은 FL에서 가장 높았고, RBGW에서 낮았다. Cystein과 methionine의 함량은 처리간에 통계적인 유의성을 나타내지 않았다. 결론적으로 수량, 총 페놀함량, 비타민 C 함량은 RBW와 RB에서 높았다. 수량, 총 페놀 함량, 비타민 C 함량 및 작업자의 눈 피로도 등을 고려 할 때 인공광원으로써 RBW가 가장 적합한 것으로 판단된다. 향후 기능성 성분 증진을 위해 듀티비 등 후속 연구가 필요하다고 판단된다. This study was carried out to investigate the effects of artificial light sources on growth and yield of hydroponically grown Peucedanum japonicum in plant factory. Treatments were composed with; florescent lamp(FL) as control, and LED lights; R:B(2:1, RB), R:B:W(2:1:3, RBW), and R:B:G:W(2:1:0.5:3, RBGW). Plant height of RBGW and FL treatments were superior to RB and RBW. Leaf weight of RBW and RB were superior to FL and RBGW. There were no significant difference of leaf length and thickness among the treatments. Lightness of leaves was same tendency with plant height. Total phenolic compound content was the high in order of RB as 105.77mg·100g<SUP>-1</SUP> GE, RBW as 92.52mg·100g-1 GE, FL as 89.08mg·100g<SUP>-1</SUP> GE, and RBGW 82.00mg·100g<SUP>-1</SUP> GE. Total flavonoids were not detected in all treatments. Vitamin C content was the highest in RB and the lowest in FL. Total dietary fiber were the highest in FL and the lowest in RBGW. There was no significant difference cystein and methionine contents among the treatments. Concludely, yield, total phenolic compounds, and vitamin C content was high in RBW and RB. We reached conclusion that RBW is best artificial light source considering yield, functionality and eye fatigability when work. We recommend to further study LED pulse and duty rates for increasing functionality.
